Wet fly. Dry fly. Indicator. Tenkara. Rapala. who cares? I've never understood why some folks think their preferred method is the only one that's legit. If they're fishing legally, who cares? A single hook Rapala or other lure would probably be down-right deadly on larger park fish. I've never tried it, but I sure wouldn't tell someone they weren't fishing properly if they tried it. Life's too short to worry about whether or not someone is fishing a nymph. Good grief.
